Research in my laboratory employs multidisciplinary approaches to study the cellular and molecular neurobiology of cell-autonomous circadian clocks and the signal transduction pathway responsible for circadian photoentrainment. The aims of current projects are to study: 1) the role of microRNAs (miRNAs) and other signaling molecules in the local temporal coordination of cell- and tissue-specific circadian clocks; 2) mutual interactions between the circadian clock mechanism, inflammatory signaling and metabolism; and 3) the mechanisms linking circadian rhythm disruption with metabolic disorders such as obesity and diabetes, and with pathological changes in neuroprotective responses to stroke.
